Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.

Big Idea:
Do your kids love doing the robot dance move?! Get them excited about measurement with dancing and a culminating project that is sure to enhance their understanding of nonstandard measurement.
